Symfony的过滤器不工作

Question

我的架构：

Poster: 
    actAs: 
    Timestampable: ~ 
    Sluggable: 
     fields:[name] 
    columns: 
    id: 
     type: integer(4) 
     autoincrement: true 
     primary: true 
    name: 
     type: string(255) 
     notnull: true 
    filename: 
     type: string(255) 
     notnull: true 
    approved: 
     type: boolean(1) 
     default: false 
    start_date: 
     type: date 
     notnull: true 
    end_date: 
     type: date  
     notnull: true 
    user_id: 
     type: integer(20) 
     default: 1 
    attributes: 
    export: all 
    validate: true 
    relations: 
    User: 
     class: sfGuardUser 
     local: user_id 
     foreign: id 
     type: one 
     foreignType: many 
     foreignAlias: Posters 

我有doctrine:generate-admin生成模块poster。在列表视图中，我看到的所有领域，包括start_date和end_date过滤器。现在，问题是，这两个过滤器不能正常工作。例如我提供了一个范围Start Date和压制filter，在响应页面，我看到了网页调试工具的SQL queries标签但我没有看到根据所提供的约束制约查询的任何指示。我刚看到这一点：

SET NAMES 'UTF8' 
0.00s, "doctrine" connection 

SELECT COUNT(*) AS num_results FROM poster p 
0.00s, "doctrine" connection 

SELECT s.id AS s__id, s.first_name AS s__first_name, s.last_name AS s__last_name, s.email_address AS s__email_address, s.username AS s__username, s.algorithm AS s__algorithm, s.salt AS s__salt, s.password AS s__password, s.is_active AS s__is_active, s.is_super_admin AS s__is_super_admin, s.last_login AS s__last_login, s.created_at AS s__created_at, s.updated_at AS s__updated_at FROM sf_guard_user s 
0.00s, "doctrine" connection 

SELECT p.id AS p__id, p.name AS p__name, p.enabled AS p__enabled, p.layout AS p__layout, p.created_at AS p__created_at, p.updated_at AS p__updated_at, p.slug AS p__slug FROM place p 
0.00s, "doctrine" connection 

SELECT p.id AS p__id, p.name AS p__name, p.filename AS p__filename, p.approved AS p__approved, p.start_date AS p__start_date, p.end_date AS p__end_date, p.user_id AS p__user_id, p.created_at AS p__created_at, p.updated_at AS p__updated_at, p.slug AS p__slug FROM poster p LIMIT 10 
0.00s, "doctrine" connection 

SELECT s.id AS s__id, s.first_name AS s__first_name, s.last_name AS s__last_name, s.email_address AS s__email_address, s.username AS s__username, s.algorithm AS s__algorithm, s.salt AS s__salt, s.password AS s__password, s.is_active AS s__is_active, s.is_super_admin AS s__is_super_admin, s.last_login AS s__last_login, s.created_at AS s__created_at, s.updated_at AS s__updated_at FROM sf_guard_user s WHERE (s.id = '2') LIMIT 1 

现在，随着Poster模型Timestampable，有created_at场。我试图给一个范围内这一领域过滤结果，并在查询选项卡，我现在看到

SELECT COUNT(*) AS num_results FROM poster p WHERE p.created_at >= '2011-12-15 00:00:00' AND p.created_at <= '2011-12-24 23:59:59' 

的是，在symfony中的错误吗？请帮忙。

UPDATE：好吧，我做了一个小调查，发现存在BasePosterFilter.class.php没有相应addFieldNameColumnQuery功能。那么，是默认的symfony行为还是一些错误？

Answer 1

Symfony的不创造任何addFieldNameColumnQuery为Doctrine（或addFieldNameColumnCriteria为Propel），而只是字段“映射”波谷自己的类型（数字，文本，布尔，日期，ForeignKey的），因为你在BaseMyModelFormFilter的getFields()见类，在使用输入过滤器时分配正确的过滤器。

相反，如果添加了一个新的领域，说myfield，你必须创建一个功能addMyfieldNameColumnQuery（或addMyfieldNameColumnCriteria），以允许Symfony的获得，并添加正确的SQL过滤器。
